Housed in an 8-SOIC (3.90 mm width) package, the MAX3085ECSA+ is a surface-mount part that shares the standard SOIC-8 footprint.
The MAX3085ECSA+ carries an Active product status from Maxim (now part of Analog Devices), with ROHS3 compliance. There is no last-time-buy notice or obsolescence risk on this line.
The MAX3085ECSA+ is a functional equivalent to the SN75176 in the same 8-SOIC footprint, half-duplex, 5 V RS-485 transceiver role. However, the SN75176 is a 5 V part with a wider supply tolerance; verify the pinout and receiver hysteresis (100 mV on the MAX3085) match your design before substitution.
The MAX3485ECSA+ is a 3.3 V supply variant of the same transceiver family, also half-duplex and 500 kbps. The MAX3085ECSA+ runs on 5 V. They are not pin-compatible for supply voltage — choose based on your system's logic rail.
